What are two coplanar lines that never intersect?
Parallel Lines.
What variable (or letter) do we use for slope?
m
What is the name of the following equation of line?
y - y1 = m(x - x1)
Point - slope.
Same side angles are....
Supplementary
What are two noncoplanar lines that never intersect?
Skew Lines.
Perpendicular lines have what kind of slopes?
Opposite reciprocals.
What does the b represent in y = mx + b?
y - intercept
If alternate interior angles are congruent, then what are opposite exterior angles?
Congruent
What do we call angles that are in the same position?
Corresponding angles.
Parallel lines have what kind of slopes.
The same slopes.
What do slope - intercept and point - slope equations have in common?
m is the slope in both.
There are three types of angle pairs that are supplementary, name all three.
Same side interior, same side exterior, linear pair.
What is the name of the line that intersects two parallel lines?
Transversal.
Slope, or rise over run, is defined as the what? (Hint: What is the scientific definition?)
The rate of change.
Tara reserves a party room with a deposit of $500 and then must pay $7.50 per person.
What does the 7.50 represent in line form?
The slope.
Two lines that are perpendicular to the transversal are....
Parallel
Angle pairs formed by a transversal are one of what two terms?
Supplementary or congruent.
Are these lines parallel, perpendicular, or neither?
y = 7/2x + 12
y = 2/7x - 11
Neither.
